...have the 60D there's no reason to change. The difference in image quality is not big enough to justify that extra work to change the equipment. The K-5 from Pentax has an even better image quality (and a better weather sealed body and built-in image stabilizer that works with any lens and a nice speed and...) - so what?

I couldn't agree more, the 60D was and still is a very good camera. Definitely not worth spending more money on another one..
